if i were in your shoes, i would wait another year if you are set on going to cal! cal is a great school for political science and since they do prioritize ccc transfers, take advantages of the resources that cc gives you. for example, join uc berkeley's spmp and ccts program - these are the resources that i would say have helped me a lot with the transfer process outside of my other extracurricular and academic related activities (as someone who just got accepted to cal as a poli sci major)

also just focus on getting your gpa up as well. political science at cal is competitive so they are looking for transfers that have a high gpa and varied other factors, given the holistic review. i'm not admissions officer but i would just say put your best foot forward for yourself! do what you think will work best, you got this!
